ALL of the newer, high-BC .270 bullets up to 150 grains are designed to stabilize in the standard 1-10 twist, and even the 170-grain Berger will at typical Western elevations as long as the weather's not too cold. (This also means it will stabilize in typical warm-weather African hunting, though you're not likely to use it.) I know this not from theory but from actually shooting all of 'em in a 22-inch barreled Model 70 .270.
But I also realize you're going to go ahead with your rifle nut theories anyway. Have fun!
